in Figure 1. Use PVC or ABS pipe nipple for sprinkler

connection.

rolling over a sprinkler exists, the swing joint will flex

preventing damage to the lateral or main lines. On a new

installation in raw ground where the sprinklers are to be

initially installed above the finished grade and lowered

common and practical procedure which eliminates the

problem of dirt being accidentally introduced into the

lateral lines when a riser is changed.
